Thanks for all comments guys- it helps a lot.
Before I’ll dive into modeling details I wanted to check if my idea of composition will play well with shapes like that so I’ve modeled quick dummy of ship’s body, duplicated it and arranged into position in which I want to have two main ships in the scene. Then I’ve changed camera to 20 mm one to get longer shots and played around for a moment to see what possibilities are there. Right now I am in doubt choosing between 2nd and 4th option- 2nd gives opportunity of displaying explosion of “falling down” ship, on the other hand in shot 4 winner of this duel will look more “heroic” with bow and galion high abowe point of view. Other two are not bad as such but I do not think they are proper for that type of ilustration- 1 allows to show entire scene in detail but lacks “movement”- is very horizontical and kind of boring, 3rd- although quite nice and dynamic - does not allow to show off all details of ships. I guess I’ll have to do it once again with sails on.
